Abstract
The present disclosure describes a method and an apparatus that can enhance the slurry oxidizability for a chemical mechanical polishing (CMP) process. The method can include securing a substrate onto a carrier of a polishing system. The method can further include dispensing, via a feeder of the polishing system, a first slurry towards a polishing pad of the polishing system. The method can further include forming a second slurry by enhancing an oxidizability of the first slurry, and performing a polishing process, with the second slurry, on the substrate.
